My current research focuses on modeling Lynch syndrome (LS) associated DNA mismatch repair gene variants in human embryonic stem cells using CRISPR-Cas gene editing. We aim to gather variant specific functional data to better inform the clinical diagnosis and stratification of LS patients.
Over the course of the last few years, we have optimized CRISPR based genome engineering to serve as a highly efficient tool to site-specifically incorporate genomic single nucleotide variant change. We aim to improve the throughput of this powerful reverse genetic approach for large scale functional genomics studies and lessen the existing technical constraints. Specifically, we aim to explore novel methodologies to improve homology directed repair outcomes for CRISPR-Cas induced DNA double-strand breaks.
We also aim to study the putative genetic modifiers of mismatch repair by modeling them in human cells and functionally evalutate them for preservation of mismatch repair function.
